GeoPulse Pinger system

GeoPulse is the survey industry’s industry standard Sub-Bottom Profiler system. Its proven success is due to its reliability, ruggedness, ease of operation and flexibility.

Sub-Seabed structures are delineated using reflexions from a selectable single frequency multi-cycle high power signal, which is transmitted from an over-the-side, towed or hull mounted platform. The signal is processed in the compact deck unit.

System Components

The system comprises the deck unit (Transmitter Model 5430A and Receiver Model 5210A) and a four transducer array (Models T135) in a tow-fish (Model 136), over the side-mount assembly (Model 132) or a bespoke hull mount arrangement, which can be configured to hold up to 16 transducers.

Edge Tech 3300-HM Full Spectrum Sonar

The 3300-HM Full Spectrum Sonar is a versatile wideband FM sub-bottom profiler that generates cross-sectional images of the seabed and collects digital normal incidence reflection data over many frequency ranges. 3300-HM transmits an FM pulse that is linearly swept over a full spectrum frequency range (also called “chirp pulse”). The reflections measured by the system are displayed as shades of gray or color on a computer monitor and may be printed on a continuous feed thermal printer. Data is stored real time into a large capacity hard drive, and can be archived to a CD/DVD ROM via the installed DVD.

Edge Tech: SB-0512i и SB-216S

Features

  • Choice of 2 tow fish depending on the application;
  • Low frequency for greater penetration
  • Pole mount option for shallow water surveys

Description

The EdgeTech 3200 Sub-bottom Profiling System is a wideband Frequency Modulated (FM) sub-bottom profiler utilizing EdgeTech’s proprietary Full Spectrum CHIRP technology. The 3200 generates high-resolution images of the sub-bottom stratigraphy in oceans, lakes, and rivers and provides penetration of up to 200m.

The 3200 comes available with a choice of three stable, low drag towfish that operate at different frequencies and can be used at depths of up to 300m. The selection of towfish depends on the sub bottom characteristics as well as the resolution and penetration requirements.

Along with a towfish, a standard 3200 systems comes with a topside processor running EdgeTech’s DISCOVER sub-bottom acquisition & processing software as well as a customer-specified length of tow cable.  Additional optional sensors are also available.

Innomar SES-2000 compact

The SES-2000 compact model is the smallest member of the SES-2000 sub-bottom profiler family. It was designed for inshore surveys in shallow-water down to 400 meters water depth, but can also be used in coastal areas.

Because of its small size and weight this system is convenient even on the smallest boat. Controlled via Ethernet using any Windows based PC or laptop it is a user friendly and affordable design, too.
